Mirror identification

Can anyone help me figure out if I have an original/1965 A body mirror?

Car is a 1965 Dart GT with remote mirror option. I haven’t been able to tell from Google searching if an original 65 mirror is twin post, or if there were other mirrors mixed in. The wires for the remote switch have been cut, so the driver’s side is likely not original.

There were quite a few parts from a 74 dart that were put on this car—my guess is that it’s from a 74. The passenger side is different than driver.

At the end of the day, I’m just trying to figure out what would have come on a 65 so that I can try to find a correct replacement.

Thanks in advance for the help.
